John McEnroe, nicknamed "Mac," is a retired American professional tennis player widely regarded as one of the greatest of all time. Known for his exceptional volleying skills, aggressive playing style, and fiery on-court temperament, McEnroe dominated the sport in the late 1970s and 1980s. He won seven Grand Slam singles titles, nine Grand Slam men's doubles titles, and one Grand Slam mixed doubles title, reaching the world No. 1 ranking in both singles and doubles. Beyond his athletic achievements, McEnroe is also remembered for his iconic rivalries with Bjorn Borg and Jimmy Connors, and his often controversial outbursts that frequently landed him in trouble with umpires and officials. Since retiring from professional tennis, McEnroe has remained a prominent figure as a tennis commentator, author, and occasional senior tour player.
